Dear Aunt,

My boyfriend takes drugs.  He says he doesn't take it a lot but I can always smell it on him when I meet him and especially when he goes out with his friends.  We have been together for almost three years now and I love him so much and I would really love to end up married with him and I would love him to stop this bad habit before he gets addicted to it.  I've done lots of researches to find out the effects drugs can have on people and it scares me that my boyfriend does it, I've told him how much I dislike him doing it and I want him to stop it, but he just doesn't seem to care or understand my feelings towards it.  How can I make him stop? Help me please!!!
